Introductions
• Hi, I’m Erin …
• Since 2011, I’ve been involved in the Islandora
project
• I’ve been involved in close to 30 different Islandora
projects, including the MIRC-DVR project at USCs
• Employed at discoverygarden, partner in the
Islandora Foundation
Project Overview •Between 1980 and 2009 USC attempted to make video
holdings available, namely the Fox Movietone News
Collection. In 2009 funding was secured for phase 1
project.
•In 2011 USC began work with Islandora and
discoverygarden to create a content model architecture,
plan metadata (PBcore, MODS, DC), and as part of a
pilot project.
•By 2012 the pilot is launched online. http://mirc.sc.edu/about

Project Overview
The MIRC-DVR content model
is tiered for preservation,
media production and
streaming web access
http://mirc.sc.edu/islandora/object/usc-test%3A174
Project Overview •Size of files required tiered systems with multiple media copies
for preservation, intermediate use and streaming access.
Project Overview
•Access to the backend is controlled by XACML policies
•Access is designed to protect early metadata
versioning for materials that cannot be described until
they are available to cataloging staff in a digital
environment.
•The backend is synced to a Filemaker database that
bolsters metadata versioning while also supporting
complex workflow tracking, from inspection of the film
original to digitization and transcoding.
Achievements•Access: Free, off-site access to low-res, watermarked video
(alongside robust descriptive metadata)
• Access: Catalog functionality (search, browse, facets,
record export)
• Access: OAI Harvesting for tiered architecture
• Preservation: A handful of digital surrogates
• Preservation: Basic Fedora infrastructure to manage them
Continued Challenges
• 220 TB of mirrored storage on Gluster clusters
•Only 100 hours of DPX assets!
• Fixity checking & policy-based management
pending
• Off-site backup for disaster recovery pending
Goals Going Forward• Free, off-site access to associated paper, still photo & audio
materials
• Durable linking & embedding
• End-user contributed metadata
• Time-based metadata
• Incremental improvements to existing workflows & interfaces, as
needed
